Subject: [PATCH] fix(ts): correctly export sub-module types (#1677)

* chore(types): build types script

Adds a script that moves the declaration files we have in `./types` to `./dist` relative to the files they intend to type.

This is the first step, we still need to change what we declare in `package.json`, add the script to the CI pipeline if we're happy with it and figure out how to type `next-auth/jwt`.

* refactor(lint): fix build-types script
